992 COLEOPTERA 



nitidus, antennis pedibusque piceo-rufis ; prothorace elongate, basi 

 utrinque bifoveolato, angulis posterioribus rectis ; elytris oblongis, 

 regulariter profunde striatis, striis impunctatis. Scutello basi 

 striato. 



Long., llmm. 



A distinct species belonging to the group with only two lateral 

 thoracic setae, and probably allied to P. sylvaticus. The thorax is 

 elongate, the length being five-sixths of the width. The sides are 

 very gently sinuate behind, the external angles being rectangular, 

 quite minutely prominent externally. The two basal foveae on each 

 side are shallow and indefinite, the outer one small. The striae on 

 the base of the scutellum are deep and definite ; the elytra are 

 narrow, parallel, flat, with slight humeral denticle, and very regular, 

 deep striation, the striae being simple. In the male the hind femora 

 are much swollen, and are angular in the middle. There is only 

 one puncture on each side of the last ventral segment. The female 

 is unknown. 



This appears to be allied to P. angustulus, Chaud. (elongatus, 

 Blanchd.), as well as to P. sylvaticus, Chaud., but does not suffi- 

 ciently agree with either description. 



Christchurch, Wakefield. A single example. 



1782. P. ovatellus, Chaudoir. (Sharp; Trans. Boy. Dub. Soc., 

 1886, p. 370.) Nigerrimus, femoribus piceis ; prothorace evidenter 

 transverso, basi utrinque unifoveolato, angulis posterioribus sub- 

 rotundatis ; elytris profunde fortiterque striatis, striis punctatis, 

 interstitio tertio bi- vel tri-punctato. Scutello basi striato. 



Long., 17mm. 



This is a peculiar species, with thorax only three-fourths of its 

 width in length ; a single deep fovea on each side the thorax, with- 

 out any trace of external plication ; only two lateral setae on the 

 thorax. The elytral stria very deep, and with two or three 

 punctures (placed variably and irregularly) on the third interstice, 

 and the shoulder and basal margin of the elytra formed as in 

 P. constrictellus and elongellus. It quite agrees with these two 

 species in appearance, but departs greatly from them by the number 

 of the thoracic setae, and by the interstitial punctures on the wing- 

 case. The male has the front tarsi much dilated, the hind femora a 

 little thickened in the middle, but not angular, and two punctures 

 on each side of the hind margin of the last ventral segment. 



New Zealand. Castelnau. Chaudoir was not acquainted with the 

 male, and I have not seen the female. Chaudoir 's examples, like 

 my own, came from Castelnau, and I feel little doubt of the correct 

 identification. 



1782. P. brOUnianilS, n.s. (Sharp; Trans. Boy. Dub. Soc., 

 Nov., 1886, p. 367.) Eobustus, niger, antennis pedibusque 

 piceis ; prothoracis lateribus rotundatis, angulis posterioribus valde 

 obtusis ; elytris profunde striatis, striis vix punctatis, hie inde parum 

 conspicue interruptis. Scutello basi minus argute plicato. 



Long., 19-20mm.
